“…Therefore, the complementation of glutathione and ascorbate is essential for maintaining the cellular equilibrium under stress conditions. Similar tendency has also been interpreted in other plant species where involvement of GR becomes a sensible trait for assessing the oxidative stress (Ding et al 2012).…”

A hydroponics experiment was carried out to study the role of hydrogen peroxide (H 2 O 2 ) through changes of oxidative stress and antioxidation activity in Salvinia natans Linn. H 2 O 2 is an active oxygen species, widely generated in many biological systems, and mediates various physiological and biochemical processes in plants. In this study, we demonstrated that exogenous H 2 O 2 causes the degradation of pigments and induces the oxidative stress and the antioxidation activity. These effects enhanced with increments of applied H 2 O 2 concentration. Application of polyamine reduced the generation and the accumulation of H 2 O 2 and modulated the enzyme activities.

“…B–D). Treating plants with specific inhibitors of the chloroplastic translation, such as lincomycin, also can block the PSII repair process, especially D1 protein synthesis in the chloroplast (Mulo et al , Ding et al , Kato et al , Tian et al ). In this study, it was shown that the positive effect of green light on alleviating F v /F m was still observed after treatment with lincomycin under CL (Fig.…”

Red and blue light are the most important light spectra for driving photosynthesis to produce adequate crop yield. It is also believed that green light may contribute to adaptations to growth. However, the effects of green light, which can trigger specific and necessary responses of plant growth, have been underestimated in the past. In this study, lettuce (Lactuca sativa L.) was exposed to different continuous light (CL) conditions for 48 h by a combination of red and blue light-emitting diodes (LEDs) supplemented with or without green LEDs, in an environmental-controlled growth chamber. Green light supplementation enhanced photosynthetic capacity by increasing net photosynthetic rates, maximal photochemical efficiency, electron transport for carbon fixation (J ) and chlorophyll content in plants under the CL treatment. Green light decreased malondialdehyde and H O accumulation by increasing the activities of superoxide dismutase (EC 1.15.1.1) and ascorbate peroxidase (EC 1.11.1.11) after 24 h of CL. Supplemental green light significantly increased the expression of photosynthetic genes LHCb and PsbA from 6 to 12 h, and these gene expressions were maintained at higher levels than those under other light conditions between 12 and 24 h. However, a notable downregulation of both LHCb and PsbA was observed during 24 to 48 h. These results indicate that the effects of green light on lettuce plant growth, via enhancing activity of particular components of antioxidative enzyme system and promoting of LHCb and PsbA expression to maintain higher photosynthetic capacity, alleviated a number of the negative effects caused by CL.

“…Silencing of GR by RNA interference attenuated GR activity in tobacco and tomato to increase the sensitivity to oxidative and/or chilling stresses (Aono et al 1995;Ding et al 2009Ding et al , 2012Shu et al 2011). In contrast, overexpression of GR in tobacco by chloroplast transformation significantly improved tolerance to methyl viologen (MV), salt and cold stresses (Le Martret et al 2011).…”

Gene knockout of glutathione reductase 3 results in increased sensitivity to salt stress in rice

Glutathione reductase (GR) is one of important antioxidant enzymes in plants. This enzyme catalyzes the reduction of glutathione disulfide (GSSG) to reduced glutathione (GSH) with the accompanying oxidation of NADPH. Previously, we showed that salt-stress-responsive GR3 is a functional protein localized in chloroplasts and mitochondria in rice. To learn more about the role of GR3 in salt-stress tolerance, we investigated the response to 100 mM NaCl treatment in wild-type rice (WT); GR3 knockout mutant of rice (gr3); and the functional gr3-complementation line (C1). Rice GR3 was primarily expressed in roots at the seedling stage and ubiquitously expressed in all tissues except the sheath at heading stage. GR3 promoter-GUS was expressed in the vascular cylinder and cortex of root tissues in rice seedlings, vascular tissue of nodes, embryo and aleurone layer of seeds, and young flowers. Under both normal and salt-stress conditions, total GR activity was decreased by 20 % in gr3. Oxidative stress, indicated by malondialdehyde content, was greater in gr3 than the WT under salt stress. As compared with the WT, gr3 was sensitive to salt and methyl viologen; it showed inhibited growth, decreased maximal efficiency of photosystem II, decreased GSH and GSSG contents, and the ratio of GSH to GSSG. Conversely, the gr3-complementation line C1 rescued the tolerance to methyl viologen and salinity and recovered the growth and physiological damage caused by salinity. These results reveal that GR3 plays an important role in salt stress tolerance by regulating the GSH redox state in rice.
